AMESSAGE FROMTHE CHAIR

Dear Alumni and Friends,

Walking across our beautiful WashU campus and seeing students and colleagues engaged in thoughtful discussions or fun activities, I’m struck by the contrast between this bucolic setting and the turbulence that is so pervasive in the world right now

No matter where you live or where your career has taken you, I recognize that you may be personally experiencing this turbulence. You’re not alone. In higher education and across science, the challenges are significant.

At the same time, our WashU Chemistry community is a tremendous source of hope.

Whether it is witnessing the creativity and drive of our current students, seeing our faculty and staff innovating to improve research and education, or hearing from you as alumni and friends about all of the ways you are creating positive change in the world (why we're launching the Distinguished Alumni Award!), I know that together we are doing amazing things. May the stories in this newsletter bring you the same sense of hope!

Sincerely,

STAY CONNECTED!

Dedication of the display honoring Professor Joseph W. Kennedy

On July 23 ,2024, the Chemistry Department rd held a dedication of the display honoring Professor Joseph W. Kennedy's legacy to the Chemistry Department, WashU campus, and his contribution to the scientific community at large.

Along with his colleagues Arthur C. Wahl and Glenn T. Seaborg, Professor Kennedy made history in 1941 by discovering the element plutonium. Professor Kennedy served as chairman of the Chemistry Department at Washington University from 1946 - 1956. His research interests included determining the chemical properties of new elements and applying isotopic-tracer techniques to examine the diffusion of reaction kinetics. The Chemistry Department's annual Kennedy Lecture Series is also named after the professor. Read more at the Department News Page

Badge from Los Alamos Laboratory
During World War II, Professor Kennedy worked on the Manhattan Project and led the Chemistry and Metallurgy Division as the Division Leader from 1943 until 1945. In 1946, President Truman awarded Professor Kennedy the Medal of Merit, the highest civilian decoration of the United States. The Medal of Merit

RESEARCH REVEALS HOW FRUCTOSE IN DIET ENHANCES

TUMOR GROWTH New research from Washington University in St. Louis shows that dietary fructose promotes tumor growth in animal models of melanoma, breast cancer and cervical cancer. However, fructose does not directly fuel tumors, according to the study published Dec. 4 in the journal Nature. Instead, WashU scientists discovered that the liver converts fructose into usable nutrients for cancer cells, a compelling finding that could open up new avenues for care and treatment of many different types of cancer “Our initial expectation was that tumor cells metabolize fructose just like glucose, directly utilizing its atoms to build new cellular components such as DNA We were surprised that fructose was barely metabolized in the tumor types we tested,” said the study’s first author, Ronald Fowle-Grider, a postdoctoral fellow in Patti’s lab Read more at the Source

CHEMISTRY DEPARTMENT UNVEILSNEWNAMED LECTURESERIES

This lecture series honors the late Professor Peter Xavier Armendarez, the first Hispanic graduate student in the Department of Chemistry. The creation of this lecture series was spearheaded by Isaac Fuentes (a graduate student in the Birman group) and the Chemistry Graduate Student Advisory Committee (CGSAC).

Dr. Armendarez was a first-generation college student who joined the Air Force after graduating from Loyola Marymount University. Originally a nuclear scientist in the Air Force, his military career sent him to Washington University in St. Louis, where he joined Arthur Wahl's lab as a graduate student. After earning his master's degree from WashU, Peter continued his education at the University of Arizona, where he earned his PhD in physical chemistry

INMEMORIAM-DR.RONALDLOVETT, PROFESSOREMERITUS

Remembrance written by Prof Lee Sobotka Ronald A. Lovett passed away after a long illness Friday, April 18, 2025. Ron was a brilliant theorist from the Kirkwood school of statistical mechanics. Following his PhD with Frank P. Buff at the University of Rochester, Ron went to Bell Labs (The “Idea Factory”), where he worked with Frank H. Stillinger. In 1967, Ron came to Washington University, where he joined the Department of Chemistry as its second theorist. Throughout his career, Ron worked on subtle interfacial phase issues. Ron was a superb mathematician, a creative programmer, and at times an innovative experimentalist. For years, he taught advanced statistical mechanics, quantum mechanics, and the PChem laboratory. His response to questions was always the same: enough discussion to define the question, he then disappeared for a few days, returning with TeXed notes, with Mathematica plots inserted, explaining the subject with clarity rarely found outside of the texts written by Landau-Lifshitz and Feynman. Some of us cherish notebooks filled with these “Lovett notes”.

Ron was an avid sportsman who would regularly play basketball, handball, and hockey as well as orchardist with a farm in Calhoun County. He and his wife Eva grew dozens of apple varieties, some experimental and others not enjoyed for generations. Trips to Eva and Ron’s farm generated life-long memories for many.
